From the time of my earliest memories, I have been fascinated by world
history and geography and captivated by maps. Today I teach global
historical geography to as wide of an audience as possible, and
I blog on the geography of current global
events (see geocurrents.info). I am a
co-author of a college textbook on world geography, and several of my
courses, are available to the public as
podcasts. My academic research focuses primarily on the history of
foundational geographical ideas and secondarily on the geohistory of
the Cordillera of Northern Luzon in the Philippines. I also write on
environmental philosophy and politics. These varied interests come
together in my speculative fiction, which aims to be entertaining,
intellectually stimulating, and geohistorically plausible.

History without Geography, like a dead carkasse, hath neither
life, nor motion ... History therefore and Geography, like two Fires
or Meteors which Philosophers call Castor and Pollux, if joyned
together, crown our reading with delight and profit; if parted,
threaten both with a certain shiprack.
